[M4IF Technotes] Re: Reference Code ISO/IEC 11164-5

[Umang Garg]

Dear Ralph,
Further to your suggestion ( below) of building our own *.lib files for 
MPEg-4 AAC; I will like to know want to know what is the difference 
between:
libisomp4 and libisomedia
They seem to have the same set of source files except the directory 
containing the source files  for Libisomp4 contains one additonal file 
called MJ2Atoms.c
Best Regards,
